PROFILE
Vidar Stiernström
During December 2024, work in the GEOS-DEV/GEOS repository centered on developing an explicit time integration solver for rate-and-state friction, utilizing C++ and XML within a finite element and physics simulation context. The approach incorporated a Runge-Kutta 3(2) method with a PID-based adaptive time-stepping controller, which was integrated into the existing physics solver framework. Updates to contact field definitions ensured compatibility with the new solver, supporting robust data handling and model integration. This feature reduced the need for manual time-step adjustments, enhancing simulation stability and reliability. No bug fixes were recorded, as the focus remained on feature development and solver robustness.
